Salisbury clash also confirmed
The sides also famously faced off at Wembley in the 2008 FA Cup final, with Kanu's strike securing a narrow victory for the Blues.
Meanwhile, Pompey's first friendly of the summer will be a trip to Salisbury on Saturday, July 1 (3pm kick-off).
Noel Hunt and Gary Roberts scored in a 2-2 draw when the sides met at the Raymond McEnhill Stadium last July.
